Ukugaya kuyindlela evame ukusetshenziswa yokuqeda indawo yokuvala ama-valve ohlelweni lokukhiqiza.Ukugaya kungenza indawo yokuvala i-valve ithole ukunemba okuphezulu kobukhulu, ubuhwaqane bomumo wejiyomethri kanye nokuqina kwendawo, kodwa ngeke kuthuthukise ukunemba kokuma okuhambisanayo phakathi kwezindawo ezibekwe uphawu.Ukunemba kwe-dimensional yendawo yokuvala i-valve yomhlaba ngokuvamile i-0.001 ~ 0.003mm;ukunemba komumo wejometri (njengokungalingani) ngu-0.001mm;ubukhulu bobuso bungu-0.1~0.008.
Isimiso esiyisisekelo sokuvala ukugaya kwendawo sihlanganisa izici ezinhlanu: inqubo yokugaya, ukunyakaza kokugaya, isivinini sokugaya, ukucindezela kokugaya kanye nemvume yokugaya.
1. Inqubo yokugaya
Ithuluzi lokugaya kanye nobuso bendandatho yokuvala kuhlanganiswe kahle, futhi ithuluzi lokugaya lenza ukunyakaza okuyinkimbinkimbi kokugaya eduze kwendawo ehlangene.Ama-abrasives afakwa phakathi kwethuluzi lokubopha kanye nengaphezulu lendandatho yokuvala.Lapho ithuluzi lokugoqa kanye nobuso bendandatho yokuvala kunyakaza ngokuhlobene, ingxenye yezinhlamvu ezilumayo ku-abrasive izoshelela noma igingqike phakathi kwethuluzi lokubopha kanye nengaphezulu lendandatho yokuvala.ungqimba lwensimbi.Iziqongo ezingaphezulu kwendandatho yokuvala ziqala phansi, bese ijometri edingekayo ifinyelelwa kancane kancane.
Ukugaya akuyona nje inqubo yemishini yama-abrasives ezinsimbi, kodwa futhi isenzo samakhemikhali.Amafutha ku-abrasive angenza ifilimu ye-oxide ebusweni ukuze icutshungulwe, ngaleyo ndlela kusheshiswe inqubo yokugaya.
2 . ukunyakaza kokugaya
Lapho ithuluzi lokugaya kanye nobuso bendandatho yokuvala kunyakaza ngokuhlobene, isamba sezindlela zokushelela ezihlobene zephuzu ngalinye ebusweni bendandatho yokuvala ukuya ethuluzini lokugaya kufanele lifane.Futhi, indlela yokunyakaza okuhlobene kufanele ihlale ishintsha.Ukushintsha njalo kwesiqondiso sokunyakaza kuvimbela uhlamvu ngalunye olulumayo ukuthi lungaphindeli umkhondo walo ebusweni bendandatho yokuvala, ukuze kungabangeli izimpawu zokugqoka ezisobala futhi kwandiswe ubulukhuni bobuso bendandatho yokuvala.Ukwengeza, ukuguqulwa okuqhubekayo kwesiqondiso sokunyakaza akukwazi ukwenza i-abrasive isatshalaliswe ngokulinganayo, ukuze insimbi ebusweni bendandatho yokufaka uphawu ingasikwa ngokulinganayo.
Nakuba ukunyakaza kokugaya kuyinkimbinkimbi futhi isiqondiso sokunyakaza sishintsha kakhulu, ukunyakaza kokugaya kuhlale kwenziwa eduze kwendawo yokubopha ithuluzi lokugaya kanye nobuso bendandatho yokufaka uphawu.Kungakhathaliseki ukuthi ukugaya okwenziwa ngesandla noma ukugaya ngomshini, ukunemba komumo wejometri wendandatho yokuvala uphawu kuthinteka kakhulu ngokunemba komumo wejometri wethuluzi lokugaya kanye nokunyakaza kokugaya.
3. isivinini sokugaya
Ukusheshisa ukunyakaza kokugaya, kuphumelela kakhulu ukugaya.Ijubane lokugaya liyashesha, izinhlayiya ezilumayo zidlula ngaphezulu kwendawo yokusebenza ngesikhathi seyunithi, futhi insimbi eyengeziwe iyanqanyulwa.
Isivinini sokugaya ngokuvamile singu-10~240m/min.Kumathuluzi okusebenza adinga ukunemba okuphezulu kokugaya, isivinini sokugaya ngokuvamile asidluli ku-30m/min.Ijubane lokugaya lendawo yokuvala i-valve lihlobene nempahla yendawo yokuvala.Ijubane lokugaya lendawo yokuvala yethusi nensimbi eyi-cast yi-10 ~ 45m/min;indawo yokuvala yensimbi eqinile kanye ne-alloy eqinile yi-25 ~ 80m / min;indawo yokuvala yensimbi engagqwali ye-austenitic 10 ~ 25m/min.
4. ukucindezela kokugaya
Ukusebenza kahle kokugaya kukhuphuka ngokunyuka kwengcindezi yokugaya, futhi ingcindezi yokugaya akufanele ibe phezulu kakhulu, ngokuvamile i-0.01-0.4MPa.
Lapho ugaya indawo yokuvala yensimbi ekhonjiwe, ithusi nensimbi engagqwali ye-austenitic, ukucindezela kokugaya kungu-0.1~0.3MPa;indawo yokuvala yensimbi eqinile nengxubevange eqinile ingu-0.15~0.4MPa.Thatha inani elikhulu lokugaya okumaholoholo kanye nenani elincane lokugaya kahle.
5. Isibonelelo sokugaya
Njengoba ukugaya kuyinqubo yokuqeda, inani lokusika lincane kakhulu.Ubukhulu besibonelelo sokugaya buncike ekunembeni komshini kanye nokuqina kwendawo yenqubo yangaphambilini.Ngaphansi kwesisekelo sokuqinisekisa ukususwa kweminonjana yokucubungula yenqubo yangaphambilini kanye nokulungisa iphutha lejometri lendandatho yokuvala, encane isibonelelo sokugaya, kungcono.
Indawo yokuvala ngokuvamile kufanele igaywe kahle ngaphambi kokugaya.Ngemuva kokugaya kahle, indawo yokuvala ingafakwa ngokuqondile, futhi isabelo esincane sokugaya yilesi: imvume yobubanzi ngu-0.008 ~ 0.020mm;imali yendiza ngu-0.006 ~ 0.015mm.Thatha inani elincane uma ukugaya okwenziwa ngesandla noma ukuqina kwempahla kuphezulu, futhi uthathe inani elikhulu uma ukugaya okuwumshini noma ukuqina kwempahla kuphansi.
Indawo yokuvala yomzimba we-valve ayilungile ukuthi igaywe futhi icutshungulwe, ngakho-ke ukujika okuhle kungasetshenziswa.Ngemuva kokuqeda ukuphenduka, indawo yokuvala kufanele ibe lukhuni ngaphambi kokuqedwa, futhi imvume yendiza ingu-0.012~0.050mm.
